Composite laminate

Abstract

A composite laminate includes a metal foil layer, a silane layer, a strengthening adhesive layer, and a hydrocarbon resin layer. The silane layer is disposed between the metal foil layer and the hydrocarbon resin layer. The strengthening adhesive layer is disposed between the silane layer and the hydrocarbon resin layer.

What is claimed is: 
     
       1. A composite laminate, comprising:
 a metal foil layer; 
 a hydrocarbon resin layer; 
 a silane layer disposed between the metal foil layer and the hydrocarbon resin layer, wherein the silane layer has a silane compound having a double bond functional group, and the silane compound having the double bond functional group has a structure of chemical formula R 1 —Si(OR 2 ) 3 , wherein R 1  is C 2  to C 8  alkenyl and R 2  is C 1  to C 8  alkyl; and 
 a strengthening adhesive layer disposed between the silane layer and the hydrocarbon resin layer, wherein a material of the strengthening adhesive layer comprises a compound having 3 or more double bond functional groups and a polymerization initiator, 
 wherein the compound having 3 or more double bond functional groups is trimethylallyl isocyanurate or the polyhedral oligomeric silsesquioxane having 3 or more double bond functional groups, which comprises octavinyl-POSS. 
 
     
     
       2. The composite laminate of  claim 1 , wherein the silane compound having the double bond functional group has a structure of chemical formula R 1 —Si(OR 2 ) 3 , wherein R 1  is vinyl or allyl and R 2  is CH 3  or C 2 H 5 . 
     
     
       3. The composite laminate of  claim 1 , wherein the silane compound having the double bond functional group is selected from the group consisting of vinyl trimethoxysilane, vinyl triethoxysilane, vinyl tri(2-methoxyethoxy)silane, vinyl triisopropoxysilane, allyltrimethoxysilane, and allyltriethoxysilane. 
     
     
       4. The composite laminate of  claim 1 , wherein a 90° peel strength of the strengthening adhesion layer is from 0.5 kg/cm to 0.54 kg/cm. 
     
     
       5. The composite laminate of  claim 1 , wherein based on 1 part by weight of the compound having 3 or more double bond functional groups, the polymerization initiator is 0.01-0.3 parts by weight. 
     
     
       6. The composite laminate of  claim 5 , wherein the polymerization initiator is organic peroxide. 
     
     
       7. A double-sided composite laminate, comprising:
 a first metal foil layer; 
 a second metal foil layer; 
 a hydrocarbon resin layer disposed between the first metal foil layer and the second metal foil layer; 
 a first silane layer disposed between the first metal foil layer and the hydrocarbon resin layer; 
 a first strengthening adhesive layer disposed between the first silane layer and the hydrocarbon resin layer; 
 a second silane layer disposed between the second metal foil layer and the hydrocarbon resin layer; and 
 a second strengthening adhesive layer disposed between the second silane layer and the hydrocarbon resin layer, 
 wherein the first silane layer and the second silane layer have a silane compound having a double bond functional group, and the silane compound having the double bond functional group has a structure of chemical formula R 1 —Si(OR 2 ) 3 , wherein R 1  is C 2  to C 8  alkenyl and R 2  is C 1  to C 8  alkyl, 
 wherein a material of each of the first strengthening adhesive layer and the second strengthening adhesive layer comprises a compound having 3 or more double bond functional groups and a polymerization initiator, 
 wherein the compound having 3 or more double bond functional groups is trimethylallyl isocyanurate or the polyhedral oligomeric silsesquioxane having 3 or more double bond functional groups, which comprises octavinyl-POSS.
